Definitions

  • This invention relates generally to a coated article with a solar control coating having multiple metal functional multi-film layers comprising at least one infrared reflective film and at least one absorptive film.
  • Solar control coatings block or filter selected ranges of electromagnetic radiation, typically radiation in the infrared region and/or ultraviolet region of the electromagnetic spectrum. These solar control coatings are placed on transparencies, such as windows, to reduce the amount of selected ranges of solar energy entering a building. This reduces the heat buildup inside the building. Coated articles with a solar-control coating are described for example in US2013/057951 A1 , US2011/236715 A1 , US2013/216860 A1 , and DE102012207561 A1 .
  • SHGC solar heat gain coefficient
  • the light to solar gain (LSG) ratio is the ratio of the transmittance of visible light divided by the SHGC.
  • the overall heat transfer coefficient (U factor) is a measure of heat loss, e.g., through the window.
  • While solar control coatings provide good solar insulation properties, it would be useful to improve the solar control properties of these coatings. For example, it would be useful to decrease the SHGC and/or to increase the light to solar gain (LSG) ratio.
  • LSG light to solar gain
  • the thicknesses of the infrared reflective metal layers could be increased. However, this would also make the solar control coating more reflective of visible light. Consumers prefer transparencies with high visible light transmittance but low visible light reflectance (both interior and exterior visible light reflectance). Further, increasing the thicknesses of the infrared reflective metal layers increases the sensitivity of the solar control coating to random or systematic variations in the thicknesses of the films making up the coating. This can alter or adversely impact upon the performance of the coating or the aesthetics of the coating. Additionally, increasing the thicknesses of the infrared reflective metal layers tends to decrease the durability of the coating to chemical and/or mechanical attack. Moreover, the accessible regions of the aesthetic/color space that are most broadly appealing and that can be reached using conventional solar control coatings employing one or more periods of dielectric/silver/dielectric structures, are constrained by the designs of conventional solar control coatings.
  • a solar control coating that provides enhanced solar control and/or aesthetic performance.
  • a solar control coating having a low solar heat gain coefficient (SHGC) to prevent heat buildup inside of a building.
  • SHGC solar heat gain coefficient
  • LSG high light to solar gain ratio
  • a high LSG indicates good solar heat blocking while allowing visible light to pass through the coating. This improves the natural lighting inside the building.
  • a non-heat-treated solar control coating having one or more of the above advantages.
  • the present invention provides a coated article and an insulating glass unit (IGU) with a solar control coating as set forth in appended independent claims 1 and 11. Specific variants of the coated article are presented in appended dependent claims 2 to 10.
  • the solar control coating provides 3 mm reference insulating glass unit (3 mm reference IGU) values of luminous transmittance (T) of not greater than 64 percent, a solar heat gain coefficient (SHGC) of not greater than 0.29, and a light to solar gain (LSG) ratio of at least 1.64.
  • the solar control coating provides 6mm reference insulating glass unit (6mm reference IGU) values of luminous transmittance (T) of not greater than 64 percent, a solar heat gain coefficient (SHGC) of not greater than 0.29, and a light to solar gain (LSG) ratio of at least 1.85.
  • 6mm reference IGU 6mm reference insulating glass unit
  • the solar control coating can be a non-heat-treated solar control coating.
  • the term “over” means farther from the substrate (or base layer) on which the coating layer or film under discussion is located.
  • a second layer located “over" a first layer means that the second layer is located farther from the substrate (or base layer) than is the first layer.
  • the second layer can be in direct contact with the first layer.
  • one or more other layers can be located between the first layer and the second layer.
  • film means a region having a chemically distinct and/or homogeneous composition.
  • a “layer” comprises one or more “films”.
  • a “coating” comprises one or more "layers”.
  • polymer or “polymeric” include oligomers, homopolymers, copolymers, and terpolymers, e.g., polymers formed from two or more types of monomers or polymers.
  • ultraviolet radiation means electromagnetic radiation having a wavelength in the range of 100 nm to less than 380 nm.
  • visible radiation or “visible light” mean electromagnetic radiation having a wavelength in the range of 380 nm to 780 nm.
  • infrared radiation means electromagnetic radiation having a wavelength in the range of greater than 780 nm to 100,000 nm.
  • solar infrared radiation means electromagnetic radiation having a wavelength in the range of 1,000 nm to 3,000 nm.
  • thermal infrared radiation means electromagnetic radiation having a wavelength in the range of greater than 3,000 nm to 100,000 nm.
  • optical thickness means the geometric thickness of the material multiplied by the refractive index of the material at a reference wavelength of 550 nm. For example, a material having a geometric thickness of 5 nm and a refractive index of 2 at a reference wavelength of 550 nm would have an optical thickness of 10 nm.
  • tempered or heat-treated mean that the article or coating under discussion has been heated to a temperature sufficient to achieve thermal tempering, heat bending, and/or heat-strengthening.
  • This definition includes, for example, heating the article in an oven or furnace at a temperature of at least 580°C, such as at least 600°C, such as at least 620°C, for a period of time to achieve thermal tempering, heat bending, and/or heat strengthening.
  • the heating can be for a period of time in the range of 1 to 15 minutes, such as 1 to 5 minutes.
  • non-heat-treated means not tempered or heat-treated, or not designed to be tempered or heat-treated for final use.

  • Thickness values are geometric thickness values.
  • a "dopant” is a material present in an amount less than 10 wt.%, such as less than 5 wt.%, such as less than 4 wt.%, such as less than 2 wt.%. For example, less than 1 wt.%. For example, less than 0.5 wt.%. For example, less than 0.1 wt.%.
  • curable means a material capable of polymerizing or crosslinking.
  • cured is meant that the material is at least partly polymerized or cross-linked, preferably fully polymerized or cross-linked.
  • critical thickness means a geometric thickness above which a material forms a continuous, uninterrupted layer, and below which the material forms discontinuous regions or islands of the material rather than a continuous layer.
  • the term "effective thickness” refers to the theoretical geometric thickness of a material deposited below its critical thickness but at deposition parameters (e.g., deposition rate, line speed, etc.) which would provide a continuous layer of the material at the reported thickness value if it were deposited above its critical thickness. For example, if a material deposited at a deposition line speed of X cm/sec is known to form a continuous layer having a geometric thickness of 10 nm, then increasing the line speed to 2X would be expected to deposit a coating having a geometric thickness of 5 nm. However, if 5 nm is below the critical thickness of the material, then the deposited coating would not have a continuous, uniform thickness of 5 nm but would form discontinuous or islanded structures. This is referred to herein as a "layer” or a "film” having an "effective thickness" of 5 nm.
  • a “3 mm reference IGU” is defined as having two spaced apart 3 mm pieces of CLEAR glass separated by a gap of 0.5 inch (1.2 mm) filled with air, with the coating on the No. 2 surface.

  • a “reference laminated unit” is defined as having two plies of 2.1 mm clear glass connected by a 0.76 mm interlayer of polyvinyl butyral and with the coating on the No. 2 surface.
  • a reference laminated unit value means the reported value when the coating is incorporated into a reference laminated unit on the No. 2 surface.
  • solar control coating refers to a coating comprised of one or more layers or films that affect the solar properties of the coated article, such as the amount of solar radiation reflected from, absorbed by, or transmitted through the coating.
  • Optical and solar control performance values are those determined using a Perkin Elmer 1050 Spectrophotometer.
